One feature that is common in online discussions and forums is the ability to "subscribe" to certain threads/topics such that when a new reply to that topic is posted to the forum you also receive that reply via e-mail.

Unfortunately, it is not currently possible to subscribe to forum topics and other content on IgorExchange. However, we are working to add this feature.

See the Keeping yourself updated on forum posts documentation page for suggestions of methods that can be used at the moment to monitor content on IgorExchange.
